Z '0 all whom it may concern:

Be it known that I, AUGUST RosnNTHAL, residing in West Allis, inthecounty of Milwaukee and State of Wisconsin, have invented new and usefulImprovements in Straw Elevators and Stackers, ofwhich the and ensilagecutters, and has for its principal object to construct a device of thischaracter which shall possess superior advantages in point Of simplicityand general efficiency.

ik further object of the invention is to provide a stacker in whichstraw and fodder will be elevated and discharged from the stacker byoscillating and reciprocating means provided with engaging fingers. Afurther object of theinvention is to provide a jointed stacker tube andreciproeating means which may be folded without uncoupling any of theparts.

A further object of this invention is to provide a swiveled stackerwhich may be elevated or swung to any angle desired without affectingthe transmission of power to the oscillating and reciprocating means.\Vith the above, and other objects, in view, the invention consists ofthe devices and parts, or their equivalents, as hereinafter set forth.In the accompanying drawings, in which the same reference charactersdesignate the same parts'in all of the views: Figurel is a side view ofa portion of a threshing ma-; chine provided with the improved elevatorand stacker, parts broken away and other parts being in section; Fig. 2is alongitudinal sectional view of the stacker; Fig. 3 is a transversesectional view of the stacker taken on line 33 of Fig. 1; Fig. 4. is anenlarged transverse sectional view of the stacker taken on line 4 l ofFig. 1; Fig.

upon the other.

Referring to the drawings, the numeral indicates the discharge end of athreshlng nachine, andll the discharge spout or outlet thereof. Astacker supporting frame lZeXtends rearwardlv from the threshingniachlne andon this frame a rectangular stacker frame 131s plvotallysupported by means of a pivotal connection 14: mounted on the, lowerportion of said supporting frame, and a yoke 15 depends from the upperportion ofthe supporting frame and is pivotally connected to the top ofthe rectangular frame.

curved trough 16 is rigidly connected to the lower portion of therectangular frame by straps 17 and extends beneath the discharge. end ofthe discharge spout 11 of the threshing machine. This trough is curvedconcentric, horizontally, to the pivotal connection of the rectangularframe with the supporting frame thus permitting the trough to receivematerial from the discharge spout in any position of adjustment of therectangular frame desired. A

.double cranked shaft 18 is mounted medially on the rectangular frameand a stacker 19 formed of an inner section 20 and an outer dischargesection 21 connected together by a hinge joint 22 is pivotally connectedon said shaft.

A short shaft 23 mounted beneath the upper portion of thesupportingframe 12 is provided with a power transmitting wheel or pulley 2% on itsouter end and with a universal coupling 25 on its inner end. Anothershort shaft 26 mounted on the upper portion of the rectangular frame 18is connected to the universal coupling at one end and at the other endis provided with a sprocket wheel 27. The corresponding end of thedouble cranked shaft 18 is provided with a similar sprocket wheel 28 anda sprocket chain 29 connects the two wheels together.

The pivotal connections of the universal coupling connecting the innerends of the short shafts together are positioned in vertical alinementwith the pivotal bolts of the rectangular frame thus permitting the rotation of the short shafts, even though at an angle with relation toeach other, and the operation of the stacker in different positions ofhorizontal adjustment. Two oscillating bars 30 provided with both rigidand swinging depending material engaging fingers 31 and 32 respectivelyare connected to the cranked portion of the double cranked shaft attheir inner ends and their outer ends are pivotally and slidably mountedin channeled guides 33 forming part of the up: per portion of each tubesection adjacent to the hinge oint. Reciprocating bars 34 also providedwith swinging engaging fingers 32' depending therefrom are pivoted tothe outer ends of the oscillating bars and are adapted to bereciprocated thereby. The outer ends of these reciprocating bars aresupported by means of bolts 35 (only one being shown) extending throughslots provided in the discharge tube section. The arms 36 which serve topivotally connect the reciprocating bars to the oscillating bars arecurved so that said arm will clear the hinge pin 37 when the stacker isin the folded position as shown in Fig. 7. Pins 38 which extendlaterally from the oscillat ing bars and serve as pivotal connectionsbetween the said arms and the channel guides are provided withanti-friction rollers 39 to reduce the sliding friction therebetween tothe minimum. The ends of the channel guides at the joint of the tube areconnected to and supported by means of cross bars 40 which extend acrossthe stacker tube from one side to the other immediately beneath thehinge pin 37.

The ends of the hinge pin 37 project beyond the ears of the hingeportion of the stacker and have mounted thereon hook members tl and tothese hook members is connected a bail 42. A rope 4-3 connected to thebail extends toward the threshing machine and between two guide rollers44 mounted on the supporting frame and positioned directly above thepivotal connection of the rectangular frame thereto. The rope thenpasses around a small windlass mounted on top of the threshing machineand is the means whereby the outer end of the stacker is raised,lowered, and held in adjusted position. The guide rollers being mounteddirectly above the pivotal connection of the rectangular frame permitsthe stacker to be swung horizontally to any .position desired withoutaffecting the ad justment of the height of the stacker end.

The inner end &5 of the stacker is enlarged and the lower portion 41 .6of this enlargement is curved concentrically to the cranked shaft 18 andpartly overlaps the outer end of the trough 16 which is likewise curvedso-as to permit the stacker to swing on the shaft 18 without passingfrom beneath the trough. The swinging material engaging fingers areconnected to the bars and their movement limited by means of theshoulders L? and 418 formed by recessing thelower side edges of the barsfrom said edges to the openings 49 through which the fingers pass andare pivotally connected to said bars. The engaging fingers are formed bypassing rods through the openings 49 and bending said rods downwardly inthe shape of an inverted U with a part of the stems of the U-shaped rodspositioned within the recesses. so that in swinging the stems willengage the shoulders and their movement will be limited. The rigidfingers are formed in the same manner with the exception that the barsare only recessed the width of the diameter of the rods in order to holdthem rigidly to the bars. As the fingers connected to the inner portionof the oscillating bars are raised out of the material by theoscillating movement of said bars it is unnecessary to provide. fortheir swinging up against the bars during the return stroke and they arethereforerigidly connected to said bars. Y

The operation of the stacker is as follows: Material is fed to thestacker in the lower curved end thereof from the discharge spout of themachine to which it is connected by means of the trough. The materialwill be engaged first by the rigid fingers of the oscillating barsduring the downward and forward stroke of each bar and then movedupwardly into the more contracted portion of the stacker tube where itwill be engaged by the swinging fingers of the oscillating bars andmoved into the path of movement of the reciprocating bars which willfurther move the material and finally discharge it from the dischargeend of the stacker. The swinging fingers of both the oscillating andreciprocating bars will engage the material during the forward strokeand during the return will swing up against the sides of the bars andpass freely through the advancing material. By means of the doublecranked shaft, the cranked port-ions of which are opposite with relationto each other, the bars on one side are advancing the material while thebars on the other side are retreating thus providing means forcontinuously discharglng material from the stacker.

The stacker may be swung around horizontally by means of the pivotalconnection of the rectangular stacker frame to the supporting frame, andmay be raised or lowered by means of the pivotal connection of thestacker tube to the rectangular frame and the rope and Windlass. Thenovel arrangement of the trough permits these adjustments withoutinterfering with the feed ing of the material to the stacker tube. Bymeans of the hinged stacker tube and the jointed bars the stacker may befolded upon itself, by turning the cranked shaft so that the joints ofthe bars are in alinement, for convenience in moving the machine towhich the stacker is connected from place to place.

From the foregoing description of the constructlon and operation of thedevice 1t w1ll be seen that a stacker 1s provlded wh1ch is very simplein construction and efficient in operation and contains but a minimumnumber of parts.
